CONCRETE WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Dec.3,,1912.

To all whom it may concern:v

Be it known that I, Woonrom) O. SEAT, citizen of" the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented a new and useful Concrete-Wall Construction, of which thefollowing is a specification. I

This invention relates to improvements in concrete walls, and the objectof the invenattained in the use ofthe device illustrated in theaccompanying drawings, and the mvention consists in certain novel.features of the samewhich will be hereinafter first fully described andthen more particularly'pointe out in the appended claims. v j

In the drawing, I have shown a sectional perspective view of a portionof a walliembodying my invention.

In .carrying out my invention, I provide a foundation 1 which may be ofany desired size according to the building to be erected and may, ofcourse, be of any material, but I prefer to employ concrete. When thefoundation has reached theproper height a coping or facing 2 may be setin or formed upon the front side of the same so as to point where'thewall proper begins. Upon the upper surface of the foundation and thesaid facing, I then spread two lines of mortar or cement, indicated at3, which respectively follow the front and rear sides of the foundation,as clearly shown. At intervals along both these lines of cement ormortar,

I place braces or bonding bars 4 which extend diagonally upward and areprovlded at their lower ends with feet 5 resting upon the foundation andhaving spurs 6 projecting upward from their. extremities. The mainportions of these braces or bondmg bars extend upward obliquely and theupper ends of the bars are provided witn horizontally disposed heads 01sh0ulders 7 having lips 8 at their extremities. These lips 8 may beturned downward or upward and in actual practice it will be founddesirable I to have the lips of the alternate braces extend in oppositedirections. The brace bars having their lips turned downward willpreferably be provided at the ends of their heads or horizontal portions7 with lugs 9 extending slightly upward to aid in centering the blockswhich will be utilized in building'the wall. At intervals along thelines of cement or mortar I provide the horizontal tie bars 10 whichwill rest directly on the foundation and will have lips 11 at their endscorresponding to the spurs 6 at the lower ends of the brace bars 4. Theseveral brace bars and tie bars being thus placed in position, concreteblocks 12 having with the grooves fitting over the upturned spurs 6 andlips 11,, as will be readily understood, The weight of the blocks willcause "them to sink in thecement or mortar so that the space between thebhttom of the blocks and the space within the grooves in the blocks willbe entirely filled with the mortar and a close tight joint therebyeffected. The upturned spurs 6 and teeth 11 will aid in bringing theblocks into the proper position over the front and rear sides ofthe-foundation, and the blocks may be leveled and brought into the exactposition they should occupy inthe finished wall by the usual methods ofmasonry. The lips 8 at the upper endsof the brace bars are' brought intoengagement: with the grooves 13 in the upper edges of the blocks and theblocks will thus be thoroughly braced and held in their proper relativepositions. The first. course of blockshaving been thus laid,

a second row of straight tie. bars 1,,0 is laid upon the said blocks anda second row of crossed, diagonally extending brace bars 4 is alsoplaced in position upon the blocks. The m'ortaris then applied and asecond row of blocks laid upon the first row with. the joints in thesuperposed row brealn'ng' joint with the under row. The wall' may thusbe carried to any desired height in.

an expeditious manner withoutthe use of any forms and without any lossof time 0c"; casioned ordinarily by waiting for the. greenconcrete toset. The horizontal tie bars '10 may be provided with lugs 14correspondtwo ing to the lugs 9 on the bracebars 4, and 11.0

the said horizontal tie bars will be so dis posed that the alternatebars in any one row will have the lips at their ends extending inopposite directions so that the transverse bonding or tyi'n g force willbe applied to. the upper edges of one row of blocks and in the sameplane to the lower edges of the superimposed -row of blocks. In thismanner the wall will be very thoroughly braced throughout its extent.

- It will be observed on reference to the drawings that the spurs orlipsat-the ends of the'several braces and tie bars will engage the innerwall of} the groove in the blocks so that the blocks will be properlyspaced and will be effectively bonded. These lips or spurs, and the lugsadj'acentthe same, also serve as guides to aid in bringing:each'superposedblock into its proper position upon the subjacent blockso that the work involved in making the wall plumb is reduced to aminimum. The wall may be pointed up and finished in the usual manner,

and the outer surface may be given any desired ornamental appearance. Atthe proper points of the wall I will place over the blocks of the, innermember of the wall a timber seat 15 in which the .end of ajoist 16 maybe supported. I

with the walls so thatthe access of moisture and dampness to the innerwalland through the same to the-interior'of the building-will bepositively prevented. The walls may be built of thoroughly driedcompressed concrete blocks so that settling or cracking of the walls.will be reduced to a minimum, and the Walls are braced in such amannerthat the vertical position of the same will be efi'ectuallymaintained. It will be readily noted' that the corresponding edges ofthe parallel blocks are connected by the hori- 'zont-al tie-barsand'that the lower edges of the blocks in each row are connected withthe upper edges of the blocks in the parallel row by the diagonal bracesso that the two wall members will be connected and braced ag'ainststrain in every direction. If, for any reason, it is desired to 'have avery heavy wall the space between the inner and outer members may befilled with liquid cement or similar material so that a thick, solidwall will be rapidly formed without the use of any of the well knownfalse work i The advantages of the construction and of the method ofoperation will'be readily apparent to those skilled in the art to whichthe Invention appertains, and while I have described the principle ofoperation of the invention,-. together with the apparatus which I nowconsider to be the bestembodiment thereof,- I desire to have itunderstood A wall constructed as illustrated and as 7 .herein describedwill present substantially 'two independent inner and outer'wallsseparated by a continuous air space coextensive thatt-he apparatus shownis merely illustratlve, and that such changes maybe made when desired asare Within the scope of the claims appended hereto.

Having thus described my invention, what I claim is 1. A concrete wallcomprising inner and outer rows of superposed concrete, blocks having;longitudinal grooves in the'edges- I constituting the upper and loweredges of the laid rows, a filling of cementing material between thesuperposed blocks entering the their opposite ends'extending betweensuperposed blocks of the respective rows and provided at theirextremities with lips projecting in. opposite directions with respect tothe intermediate portions of the bars, the lip ends of the bars beingembedded in the cementing material, and the tie bars extendingdiagonally upward from one end toward grooves in the blocks, and tiebars having* the other end and alternating in direction from one row ofsuperposed blocks to the like blocks of the other row, the lip on oneend of a bar extending upwardly into the groove of the block andthe lipat the other end of the bar extending downwardly into, the groove at theopposite edge of the corresponding block of the other row.

2. A wall composed of spaced rows of superposed concrete blocks, eachblock having longitudinalgrooves on the edges constituting the upper andlower edges when laid in a Wall, and tie bars extending across the spacebetween the rows of blocks and having their endsentering the respectiverows ofbloc ks at the joints and terminating in lips engaging in thegrooves in the blocks,

the tie bars each extending from the joint between two blocks of one rowto the joint between two blocks'of the other row at a higher point onthe other row than the first named blocks,

v 3. A concrete wall comprising inner and outer rows' pf superposedconcrete blocks.

to the other.

4. A concrete Wall comprisinginner and outer rows of superposed concreteblocks having longitudinal grooves in the edges constituting the upperand lower edges of the laid rows, a filhngof cementing material betweenthe superposed blocks, said maierial entering the grooves in the blocks,and tie bars having their opposite ends extending between superposedblocks of the re spective rows and provided at their extremitles withlips entering the grooves in the respective blocks, the hpped ends ofthe bars being embedded 1n the cementing material, the tie barsextending diagonally upward from one end toward the other andalternating in direction from one row of supersame level in the rows ofsuperposed blocks. 15

In testimony, that I claim the foregoing as my own, I have heretoatiixed my. slgnature in the presence of two wltnesses.
